But McEvoy didn't go with his gut, using statistics instead. After his eyes lit up and the 21-year-old proclaimed no one had ever asked him such a question, McEvoy warned The Project panellists "this is my analytical side coming through".

"Looking into the future, the odds of me going to another Olympics, maybe aside from Tokyo, I'm not sure, but past that it's pretty much next to nothing," McEvoy said.

*deep breath*

"So looking at those odds and comparing them to some potential odds of where I would like to be in the future -- say 10 to 20 years from now -- the odds of working for NASA are slightly higher than they would be at racing for another Games. So I'd probably have to choose the Olympics, just based off statistics."

Okay, so he chose the Olympics over NASA but it's pretty clear he wants both.

Not long after the entire panel was left in stitches, Carrie Bickmore interjected to ask whether chlorine killed urine in the pool.

"Wait, do I urinate in the pool?" McEvoy asked, followed by more laughter.

If the 21-year-old is as much of a hit at Rio as he was on The Project, he could be making Aussie history. McEvoy has the potential to become the first Aussie swimmer to win six medals at a single Games.
